I found that AVG AntiTrack prevents Microsoft Copilot from functioning correctly in Microsoft Edge. Copilot displayed the error:
“Oops! Something happened. Can you try again?”
Disabling the AVG AntiTrack extension immediately resolved the issue. It appears that AntiTrack may be blocking or modifying authentication, cookies, session data, or browser fingerprinting information that Copilot requires.
Please investigate compatibility with Microsoft Copilot and consider adding appropriate exceptions or informing users of the conflict.
